step 2–connect motor/battery
step 1–mount esc
Mount the ESC so the power wires are as far away from other electronics as
possible, and will not interfere with the vehicle’s moving parts. Select a loca-
tion with good airflow for cooling the ESC for efficient operation.
1. MOUNT SPEED CONTROL IN VEHICLE
Use the included double-sided tape to mount ESC in vehicle (do not use glue).
Avoid contact with side walls or chassis components to avoid vibration damage.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery,
and servo as possible--These components all emit RF noise.
Note: Mount antenna as close to receiver as possible--trail excess wire off top of
antenna mast (cutting/coiling excess wire reduces radio range--2.4GHz too).
2. INSTALL ON/OFF SWITCH
Use included double-sided tape to mount switch where it will be easy to
access--select a place where it will not get damaged/switched OFF in a crash.
3. SECURE POWERCAP & POWER WIRES TO AVOID VIBRATION DAMAGE
Use the included tie-wraps to secure PowerCap to the ESC’s power wires,
then tie-wrap the power wires together or to a point on the vehicle.
Motor connection
1. INSTALL PINION GEAR & ADJUST MOTOR FOR PROPER GEAR MESH
Tighten pinion’s set screw on flat of motor shaft. Align pinion & spur gears.
A. You NEED a small amount of play between the pinion and spur gear
(about thickness of a piece of paper)–check free play at several points around
spur gear to ensure a proper mesh (just in case gears are out of round).
MAKE SURE THE PINION/SPUR GEAR MESH IS NOT TOO TIGHT!
B. Tighten motor mounting screws–Avoid using excessive force that could
break screws or strip the threaded holes in motor.
2. CHECK FOR PROPER GEARING DURING INITIAL RUNS
The brushless motor & ESC should NOT be hotter than 160°F after a 5 minute
run. Lower the gearing until both ESC & motor are under this temperature.
3. CONNECT MOTOR POWER PHASE WIRES TO MOTOR
A. Solder the speed control’s BLUE Phase ‘A’ silicone motor power wire to
the motor’s Phase “A” solder tab.
B. Solder the speed control’s YELLOW Phase ‘B’ silicone motor power wire
to the motor’s Phase “B” solder tab.
C. Solder the speed control’s ORANGE Phase ‘C’ silicone motor power wire
to the motor’s Phase “C” solder tab.
4. CONNECT MOTOR SENSOR HARNESS TO ESC
Insert the 6-pin connector of the motor’s sensor harness into ESC’s sensor
harness socket—connector is keyed and only inserts in one direction.
Battery connection
1. CONNECT ESC’S BATTERY CONNECTOR TO BATTERY PACK
Solder the ESC’s RED & BLACK battery power wires to a fully charged 1S-2S
LiPo, or 4-6 cell NiMH (1.2 VDC/cell) battery pack or to a connector.
To use battery connectors on the ESC, we suggest using low-loss high power
connectors like Dean’s Ultra Plug or the Novak Power Connector.
• Use polarized connectors. Reverse voltage will damage ESC & void warranty.
• Use a female connector on battery packs to avoid shorting of exposed contacts.
• Insulate all exposed wiring connection to avoid shorting.
NOTE: If using NiMH/NiCd batteries, the Voltage Cut-Off Circuitry must be
turned OFF (refer to the ESC Track Guide).

With ESC connected to a charged battery, receiver, & motor’s sensor harness:
1. TURN ON THE TRANSMITTER’S POWER
2. PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3. TURN ON THE SPEED CONTROL’S POWER
With transmitter at neutral (still pressing SET button), slide ESC’s switch to ON position.
4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5. RELEASE SET BUTTON AS SOON AS RED LED TURNS ON
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until green status LED turns solid green. (Motor won’t run during programming).
7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKE/REVERSE
Hold it there until the green status LED blinks green.
8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
The red status LED will turn solid red, indicating that speed control is at neutral and
that proper programming has been completed. White LED may also be on and blinking,
indicating that Dynamic Timing Advance is OFF and the timing is set to a level of 0%.
If transmitter settings are changed, the One-Touch Programming must be repeated.
If you experience any problems, turn off ESC and repeat One-Touch.
NOTE: The speed control will NOT revert back to the factory-default settings when the
One-Touch Programming is performed. Refer to ‘Data Reset’ in Custom Programming.
STEP 4-one-touch programming
transmitter adjustments
Transmitter adjustments may not be required to properly complete the One-
Touch programming. If you have any problems with the programming, adjust
your transmitter settings as listed below and repeat ONE-TOUCH PROGRAMMING.
THROTTLE CHANNEL ADJUSTMENTS
A. Set HIGH ATV or EPA to 100%. [amount of throw at full throttle]
B. Set LOW ATV, EPA, or ATL to 100%. [amount of throw at full brakes]
C. Set EXPONENTIAL to zero setting. [throttle channel linearity]
D. Set THROTTLE CHANNEL REVERSING SWITCH to either position.
E. Set THROTTLE CHANNEL TRIM to middle. [adjusts neutral position]
F. Set ELECTRONIC TRIGGER THROW to 70% throttle/30% brake (or 7:3)--best
for racing. Set to 50%/50% for full time use with reverse for best performance.
G. Set MECHANICAL TRIGGER THROW to 2/3 throttle and 1/3 brake throw position.
•NOT ALL TRANSMITTERS HAVE ALL OF THESE ADJUSTMENTS•
step 3–connect receiver
receiver connection
The ESC has a user-replaceable input harness
with a 2mm mini plug on ESC end of it and the
industry-standard connector on receiver end.
ESC works with all major brand’s new receivers
(very old receivers need wiring sequence changed in
plastic plug on receiver end-- Damage may occur
if sequence is incorrect) . For instructions on
changing the wiring sequences, visit our web site.
1. CONNECT 2mm MINI PLUG TO RECEIVER HARNESS PINS ON ESC
Insert the 2mm mini plug of receiver input harness onto the receiver harness
3-pin header on the ESC. White wire goes on the left side pin as shown above.
2. CONNECT RECEIVER HARNESS TO RECEIVER
Insert 3-pin connector of receiver harness into Ch.2 (throttle) slot of receiver.
3. INSTALL 25mm COOLING FAN ON ESC (OPTIONAL)
Press fan screws through 2 of the holes along one edge of the fan and into the 1st
gap of ESC heat sink fins. Plug fan connector onto ESC’s fan pins--note polarity.
